Not to argue, but I've run many a TBI setup without an ESC. I just disable 
code 43 and zero out the knock retard tables. Just letting you know it 
doesn't seem to be a problem since my truck runs great without the ESC with 
the stock ASDU bin timing tables. Of course, you have to set the timing per 
GM specs and the setting has to match what's in the bin. A timing light 
should agree with what the bin says. If your table says 26 degrees at idle, 
then that's what the timing light should show at idle. The problem is, there 
is a startup advance amount, cold bias, warm bias, etc. You really have to 
understand all the issues affecting timing before you can get a handle on it. 
Read BobR.'s 747spark timing only project writeup and you'll get a better 
feel for what's going on. You can also read my website for a very basic 
discussion on ignition and timing control. Its a summary of what I've read in 
the archives mostly. Its at www.customefis.com. Look under the DIY section. JW
